Emission frequency stability in single-mode-fibre optical feedback controlled semiconductor lasers
Abstract
A newly designed semiconductor laser emitter with adjustable linewidth by controlling the coupling to a single-mode fiber is described with emphasis on thermal requirements to obtain a high-frequency stability. A stable operation has been achieved during more than 1 h using an AlGaAs laser diode with optical feedback from a 50 cm-long single-mode fiber resulting in a 50-fold reduction of the spectral linewidth.
